Abstract

A specialized design methodology was proposed, based on determining the optimal ratio between the length of the afterburner chamber in a ramjet propulsion system and the mass of its fuel charge, using the criterion of achieving the maximum total thrust impulse under strict mass and dimensional constraints of the aircraft. Based on this methodology, from the perspective of maximizing flight range, an assessment is provided on the feasibility of implementing an innovative technical solution on an aircraft with varying relative elongation—specifically, an afterburner chamber of a ramjet propulsion system that can be telescopically transformed in flight.
